Description

Technical Field

[0001] This application relates to the field of dust collector technology, specifically to a reverse-blowing vibration cleaning device for a dry dust collector used in mining. Background Technology

[0002] Mining operations generate a large amount of dust, which not only seriously endangers the health of construction workers but also easily leads to various safety accidents. In order to effectively control the various dusts generated in mining operations, mine dry dust collectors are used to remove the ash from the flue gas in a dry state. This has a significant effect on solving problems such as mine dust pollution, water waste from wet dust removal, and secondary pollution of wastewater.

[0003] Chinese patent document CN221400628U discloses a high-efficiency dry dust collector for coal mines, specifically a support plate. The support plate has a suction port, and a filter cylinder is mounted on the support plate and covers the suction port. The suction port is connected to a negative pressure device. The support plate also includes a bracket and a protective cover over the filter cylinder. A motor is mounted on the bracket, and the motor is connected to a vertically aligned shaft on the filter cylinder's axis. The shaft passes through the protective cover and is connected to a brush plate that contacts the filter portion of the filter cylinder. The protective cover has a dust suction port. The negative pressure device generates negative pressure, allowing outside air to enter the protective cover through the dust suction port and be filtered by the filter cylinder. The motor drives the brush plate to rotate around the filter cylinder, thus cyclically brushing away the dust adhering to the filter cylinder, avoiding the loud noise and damage to the equipment caused by vibration cleaning.

[0004] When the brush plate brushes the filter cartridge, it needs to apply a certain amount of pressure to achieve the desired cleaning effect. However, this can easily cause the filter cartridge to break, thus affecting the overall dust removal efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this application provides a reverse-blowing vibration cleaning device for a dry dust collector used in mining.

[0006] This application adopts the following technical solution: a reverse-blowing vibration cleaning device for a dry dust collector in mining, including an upper frame, a lower frame, and a filter bag. The filter bag is cylindrical, with its top connected to the upper frame and its bottom connected to the lower frame. The top of the filter bag has an opening, and its bottom is closed.

A traction rope is provided between the vibrating ring and the rotating shaft. The outer wall of the vibrating ring is in contact with the inner wall of the filter bag. The vibrating ring is used to vibrate the filter bag and the backflush pipe.

[0008] Optionally, the mounting bracket is provided with an air pipe connected to an air source, the air pipe being used to supply air to the backflush pipe.

[0009] Optionally, each of the filter bags is provided with a backflush pipe, the bottom of the backflush pipe is closed, and the outer wall of the backflush pipe is provided with a number of air holes for blowing air toward the filter bag.

[0010] Optionally, the top of the mounting bracket is provided with a pair of bearing seats, the rotating shaft passes between the pair of bearing seats and can rotate around the bearing seats, and the output shaft of the motor is connected to the end of the rotating shaft.

[0017] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0018] like Figure 1-3 As shown, a reverse-blowing vibration cleaning device for a dry dust collector in a mine includes an upper frame 1, a lower frame 2, and a filter bag 3. The filter bag 3 is cylindrical, with its top connected to the upper frame 1 and its bottom connected to the lower frame 2. The top of the filter bag 3 has an opening, and its bottom is closed. The upper frame 1 has a mounting frame 4 at its top, and the bottom of the mounting frame 4 has several reverse-blowing pipes 5. One end of each reverse-blowing pipe 5 is connected to the mounting frame 4, and the other end extends to the lower inner side of the filter bag 3. The reverse-blowing pipes 5 blow air towards the inner wall of the filter bag 3. The top of the mounting frame 4 has a rotating shaft 6 driven by a motor 61. The outer wall of the reverse-blowing pipes 5 has a vibrating ring 7, and a traction rope 62 is provided between the vibrating ring 7 and the rotating shaft 6. The outer wall of the vibrating ring 7 is in contact with the inner wall of the filter bag 3, and the vibrating ring 7 is used to vibrate the filter bag 3 and the reverse-blowing pipes 5.

[0019] The backflush pipe 5 extends to the inner side of the filter bag 3, and its length is close to that of the filter bag 3. This allows the gas blown from the backflush pipe 5 to act more evenly on the surface of the filter bag 3, reducing pressure attenuation, increasing the contact area between the gas and the filter bag 3, and improving the dust removal effect. Furthermore, when the motor 61 drives the rotating shaft 6, the traction rope 62 can pull the vibrating ring 7 up and down. The vibrating ring 7 contains a vibrating motor and a power supply. Thus, while the backflush pipe 5 is performing backflushing, the vibrating ring 7 can move up and down inside the filter bag 3, transmitting the vibration energy generated by the vibrating motor to the filter bag 3, causing the filter bag 3 to shake. This maximizes the dust removal effect of the filter bag 3. Moreover, the backflush pipe 5 blows gas while vibrating, further enhancing the backflush effect on the filter bag 3.

[0020] The mounting frame 4 is equipped with an air pipe connected to the air source. The air pipe is used to supply air to the backflush pipe 5. The air pipe is hidden to prevent interference with the traction rope 62, thereby ensuring that the backflush of the backflush pipe 5 and the up-and-down movement of the vibration ring 7 do not interfere with each other.

[0021] Each filter bag 3 is provided with a backflush pipe 5. The bottom of the backflush pipe 5 is closed. The outer wall of the backflush pipe 5 is provided with a number of air holes 50. The air holes 50 are used to blow air towards the filter bag 3. In this way, the contact area between the backflush gas and the filter bag 3 is increased, thereby improving the dust removal efficiency.

[0022] The top of the mounting frame 4 is provided with a pair of bearing seats 63. The rotating shaft 6 passes between the pair of bearing seats 63 and can rotate around the bearing seats 63. The output shaft of the motor 61 is connected to the end of the rotating shaft 6. Under the support of the bearing seats 63, the motor 61 can reliably drive the rotating shaft 6 to rotate, thereby realizing the winding or unwinding of the traction rope 62 on the rotating shaft 6, which also realizes the driving effect on the vibration ring 7.

[0023] The top of the outer wall of the filter bag 3 and the bottom of the outer wall of the filter bag 3 are each provided with an installation ring 30. The upper frame 1 and the lower frame 2 are each provided with a plurality of installation holes 20. The plurality of installation rings 30 are screwed into the installation holes 20 respectively and in a one-to-one correspondence. The installation rings 30 and the installation holes 20 are connected by threads, which facilitates the replacement of the filter bag 3.

[0024] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
